Sunderland boss Gus Poyet was thrilled with their shock win at Manchester United.
Sebastian Larsson struck the only goal of the game in the first-half.
Even if Sunderland lose their final two games, there needs to be a huge swing of goals in Norwich's favour to keep the Norfolk club up should they fail to pick anything up at Stamford Bridge.
"This is close to a miracle," the Sunderland manager said.
"A miracle was the word I used a few weeks ago and apparently every now and again it happens.
"We thought we would have to win four matches after losing to Everton (on April 12).
"We won three and if we win one (more) we are over the line. Chelsea could help us tomorrow. I don't know if I will be able to watch.
"What we have done in the last four games is unique.
"It is special, incredible...
"We were getting no breaks. Normally that sends you down, and then you need something very special."
